At Maliepaard, Bosman Van Zaal has realised a new wide-span greenhouse for tulip forcing, equipped with full automation and mechanical dehumidification.
The greenhouse features 24 OptiDry Advanced-DX units, which actively remove the moisture produced by the tulips and help create an optimal growing climate. Thanks to the hydroloop system, excess heat can be discharged to the outside air via a water circuit and dry cooler whenever that heat is not required. This allows the energy screen and roof vents to remain closed, resulting in significant energy savings.
In addition, the greenhouse has been fitted with a new heating system, CHPand HTS (heat storage tank). The CHP supplies the business with both electricity and heat. When the heat is not immediately needed, it is stored in the HTS for efficient use later, for example during the night.
The OptiDry Advanced DX uses the natural refrigerant R290 (propane). This means lower energy consumption, an environmentally responsible solution, and a system that is prepared for future regulations.
This project is a strong example of how climate control, energy efficiency and future-proof technology come together in modern horticulture.
During our seminar, we will take a closer look at these kinds of innovative solutions and show how technology and cultivation are increasingly working together in smarter ways.
